It should be noted that from the inlet to the first of routing wheel 8 to export 11 or second outlet 12, the basic container that in same plane, transmits bottle-type, the described container of

guide channel

13,14 same maintenances is in same plane.

Routing wheel 8 is installed on the axle that supports by base 70, and base 70 also supports two

guide channels

13,14.

Routing wheel 8 comprises 24 basically identicals and equidistant clamping limb 7 forms, a plurality of clamping limbs that move radially.Fixing top dish 90a and fixing bottom dish 90b are disposed across on the turning cylinder 10 of routing wheel 8, and the strut member of each self-forming slideway 91.The bare terminal 7a of the clamp-shaped of each clamping limb 7 is supported by hold-down arm 92, so each clamping limb 7 comprises hold-down arm 92 and the bare terminal 7a that is supported by hold-down arm 92.

Even

dish

90a, 90b according to the crosswise fixed of the slideway 91 that is defined for clamping limb 7 separately describe and have illustrated the present invention, also must clearly understand, if dish 90a, the 90b of a crosswise fixed and the horizontal dish 152,153 of a rotation that is attached with clamping limb 7 are only arranged, routing wheel 8, the running principle of routing wheel 8 also remains unchanged so.

Hold-down arm 9 is installed into can revolt the effect of spring 93 and slide on guide rail 94.As shown in Figure 3, each guide rail 94 all is installed on the horizontal dish 152,153 of rotation by collet 95, and collet 95 is fixed on the horizontal dish 152,153 of rotation.Spring 93 is exerted pressure with axle mounting and to block 97 with the axis of guide 96, the support that block 97 constitutes the axis of guide 96 and roller 98.Roller 98 is revolted the effect of springs 93 and is advanced along slideway 91.

According to the distance of roller 98 between the position on the slideway 91 and consequent roller 98 and turning cylinder 10, the contraction of spring 93 significantly or more not remarkable, and guide rail 96 is in collet 95, slide on either large or small degree.

The bare terminal 7a of clamp shape comprises two and half pincers 100,101 and springs 102, two and

half pincers

100 and 101 are finished it by the effect that relatively rotates with respect to each other and revolt spring 102 and are opened motion, and its turning cylinder is basically parallel to the pivot center of the roller 98 of clamp strut member 92.

The slideway 91 of

horizontal dish

90a, 90b that each is fixing comprises corresponding to substantially with first jiao of sector (secteur angulaire) 110 of the clamping limb 7 of circular arc motion.On the rotation direction of routing wheel 8 (R8 is indicated as arrow), slideway 91 is included in second sector 111 after first jiao of sector 110, roller 98 moves near pivot center 10 in this sector, and the effect of this motion resistance spring 93 is carried out, thereby causes spring 93 to shrink.Still along the rotation direction of routing wheel 8, slideway 91 comprises the 3rd sector 112, and in this sector, roller 98 is advanced in groove 113, and groove 113 is demarcated towards fixing horizontal dish 90a, the inside of 90b by projection 114.When roller 98 was advanced in groove 113, they were away from pivot center 10 motions of routing wheel 8, and this just means that cooresponding bare terminal 7a is also away from pivot center 10 motions.Still on the rotation direction of routing wheel 8, slideway 91 comprises the 4th sector 115.

Between the 3rd sector 112 and the 4th sector 115,

dish

90a, 90b are provided with through hole 116, and translating cam 120a, 120b pass this through hole in the suitable time, shown in Fig. 3 and 5.

Under the non-existent situation of translating cam 120a, 120b, roller 98 leaves the 3rd zone 112 of slideway 91, and depicts a circular arc on whole the 4th sector 115, thereby integrates with the inlet of first guide channel 13.

As translating cam 120a, when 120b is in the appropriate location, roller 98 leans against on the chute surface 121, and near the therefore motion pivot center 10 of routing wheel 8 of corresponding bare terminal 7a.Therefore, bare terminal 7a does not integrate with first guide channel 13.When the roller 98 of bare terminal 7a entered first sector 110, bare terminal 7a got back on the common path of all bare terminal 7a.The for example inferior-quality bottle that bare terminal 7a is entrained is selected when entering second guide channel 14.

Routing wheel 8 comprises first group of clamping limb 7 and second group of clamping limb 7.The motion of first group of clamping limb 7 is by bottom slideway 91 controls of bottom dish 90b and bottom translating cam 120b, and each clamping limb 7 is attached on the horizontal dish 153 that rotates the bottom by collet 95 then.The motion of second group of clamping limb 7 is by slideway 91 controls on the top of top dish 90a and top translating cam 120a, and each clamping limb 7 is attached on the horizontal dish 152 that rotates on top by collet 95 then.The control of the motion of the control of the motion of second group of clamping limb 7 and first group of clamping limb 7 is similar.By this set, for the same radius of routing wheel 8 and identical velocity of rotation, the quantity of the clamping limb 7 on the routing wheel 8 is doubled, thereby the transportation speed of the bottles that transmit by routing wheel 8 is doubled.Advantageously, each cam 120a, 120b have its proprietary driving device, the cylinder type driving device 140a, the 140b that for example serve a dual purpose, and driving device is arranged on the outside face of fixing horizontal dish 90a, 90b.In described embodiment, routing wheel 8 is symmetrical substantially about horizontal plane P (referring to Fig. 3), roughly the midway location of wherein horizontal plane P between two slideways 91 of fixing

horizontal dish

90a, 90b of upper and lower.Fig. 3 shows the storing apparatus 150 of the near-end 151 that is used for the axis of guide 96.Storing apparatus 150 is fixed on the horizontal dish 152,153 of rotation of two annulars, and dish 152,153 is respectively the upper and lower dish of axis 10.The auxiliary dish 152,153 of two rotations is generally housed between fixing upper lateral dish 90a (it is defined for the slideway 91 of the roller 98 of first group of clamping limb 7) and the fixing lower, transverse dish 90b (it is defined for the slideway 91 of the roller 98 of second group of clamping limb 7).The cylinder 140a that for example serves a dual purpose, the driving device of 140b, the telescopic cam 120a of the through hole (or perforate) 116 among the fixing upper lateral dish 90a, the motion of 120b are passed in control.Similarly, for example the driving device of the cylinder 140b that serves a dual purpose of bottom is controlled the telescopic cam 120a that passes the through hole 116 among the fixing lower, transverse dish 90b, the motion of 120b.

Advantageously, have successively from first group the clamping limb 7 that is positioned on the fixing upper lateral dish 90a according to channel selection device of the present invention, and from second group the clamping limb 7 that is positioned on the fixing lower, transverse dish 90b.From the clamping limb 7 of fixing lower, transverse dish 90b, the clamp 7 of the upper lateral dish 90a that both sides are fixed surrounds, and on the contrary, when overlooking, clamping limb 7 is that equidistant substantially, adjacent clamping limb 7 separates with same radian.

Because no matter whether telescopic cam portion 120a, 120b exist, bare terminal 7a is towards the

inlet

11,12 of

passage

13,14, therefore the container body of bottle-type enters

corresponding passage

13,14, thereby forces the axis 10 of the main body of container away from routing wheel 8, thereby bare terminal 7a is opened.

Should be noted in the discussion above that in existing container blow molding machine, when the container of bottle-type leaves blow moulding machine, the container of each bottle-type is carried out optical check.Consider high flow capacity (magnitudes of 20 containers of per second), image processing time and the essential compactedness of machine, under ideal conditions, should in the very short time, isolate inferior-quality container, and it is discharged from a series of container.

Because transmitting is that the strut member (for example clamp) that utilizes Individual Items is carried out, thereby can discharge the container of single bottle-type.On the contrary, the traditional eduction gear that is arranged on the air transfer apparatus can be removed more than one bottle.

It is the fragmentary, perspective view of second kind of possible embodiment of the routing wheel 180 of R180 that Fig. 6 has described according to rotation direction of the present invention.Routing wheel 180 comprises the lower, transverse dish 182 that at least one is fixing, it defines the cam path that is used for follower rollers 186 in inside, follower rollers 186 belongs to clamping limb 188, clamping limb 188 can use the bare terminal 190 of clamp shape to grasp the container of bottle-type, the opening or close up by being that the cam and the roller system 191 of known type controlled of clamp 190 itself.
